Toyota Tire Pressure Sensor Light Flashing

but it is unsettling to have the upstream light flashing

After trying both VSGO and Visible Dust (all three liquids), I finally achieved a completely spot free sensor with these swabs. In addition, the type 2 swab size was just about perfect for a horizontal swipe of a D500 sensor. VSGO swabs (16mm) were too small; Visible Dust (Green APSC) were too big. The ultra swabs do need more liquid, according to Photographic Solutions (I used 7 or 8 drops), and one needs to apply adequate pressure (see their video), after getting the feel of the swabs and pressure, the third time did the trick. I got a completely black (Lightroom visualize spots display) sensor at f/16 of the empty blue sky.

I also have a Giotto Rocket Air Blaster, which I love. I decided to buy the VisibleDust blower based on the theory it will reduce the risk of blowing dust on my sensor. I don't know how real that risk actually is... The air is pushed through a filter to minimize the risk of blowing dust onto your sensor. Because of this, the air pressure you can generate is lower than for the Giotto, but I suppose you don't want too much pressure against your sensor anyway. It's sufficient for blowing dust off your lens, too. Quality is solid.

My Sony a7R II had some particles on the sensor that could not be removed by puffs from a Rocket blower. I had a photo shoot scheduled a week away so I ordered the type 3 sensor cleaning kit from B&H. Like everyone else, I was concerned about cleaning the sensor myself on a camera with built-in stabilization. I watched the videos on line then went for it. I gave the sensor a few more puffs of air, put the camera in sensor cleaning mode and let it shake the camera, left it on after previously having set the go to sleep time up to the max setting, put three drops on each side of a swab and put the proper amount of pressure to slightly bend the swab. One pass to the right, relax the pressure and one pass back to the left with the same pressure and its done. The sensor was spotless and several test shots confirmed the successful cleaning. You may want to send your stabilized camera body to the manufacturer for cleaning but I didn't have the time and my gamble paid off.

Had streaks on the sensor from too much pressure on the Arctic Butterfly (in spite of reading the directions). One pass with the Sensor Clean Solution cleaned the streaks and left no dust. Worked like a charm.

First attempt at cleaning a sensor. Correct pressure and a slow is smooth, smooth is fast mindset is needed. Took three swabs to completely clean, but ~$10 (Only because I used three swabs) for a cleaning instead of $60 (Having a "Professional" do it) is a winner. Plus, company backs their product if your camera is damaged regardless ( whether swab did the damage or user error).

For background to take picture of a tire

I use two of these at every shoot. Light enough that they don't tire out the holders, and heavy duty enough to support my shotgun microphones.

Great light for camping, hunting, or tire change on the side of the road after dark

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.
